Sanity, smoke, and regression testing are performed at different stages of software development to ensure quality and stability.

• Sanity testing is performed after a small change or bug fix to ensure that the core functionality of the software is still intact.

• Smoke testing is performed to check the basic functionality of the software after a build or release.

• Regression testing is performed to ensure that the existing functionality of the software is not affected by new changes ...read more

Severity refers to the impact of a defect on the system, while priority determines the order in which defects should be fixed.

• Severity is about the seriousness of a defect, while priority is about the order of fixing it.

• Severity is often categorized as high, medium, or low, while priority is typically assigned as high, medium, or low.

• For example, a critical defect that causes the system to crash would have high severity and high priority, while a cosmetic defect with low impa...read more

Latency time refers to the delay or time taken for a response or data to travel from its source to its destination.

• Latency time is the time delay between a request and a response.

• It is often measured in milliseconds (ms).

• Latency can be caused by various factors such as network congestion, processing time, or distance.

• High latency can result in slow response times and poor user experience.

• Examples of latency include the time it takes for a web page to load, the delay between c...read more
